Attosecond laser provides first 'movie' of fast electrons jumping band-gap of semiconductor
The entire semiconductor industry, not to mention Silicon Valley, is built on the propensity of electrons in silicon to get kicked out of their atomic shells and become free. These mobile electrons are routed ...
Bridging gap between 'internet of things' and mobile networks: Mystery of the printed diode solved
For 13 years the mystery has remained unsolved, but now Negar Sani, Ph.D. student at Linköping University's Laboratory of Organic Electronics, Campus Norrköping, has succeeded in explaining how a printed ...
Electromagnetic noise leaves birds lost in migration, study reports
Radio waves disrupt the magnetic "compass" in robins, according to a study published on Wednesday that is likely to fuel debate about the safety of electronic devices.
Device could boost image quality for phones, computers and TVs
(Phys.org) —A device created by UCLA researchers could lead to a significant leap in the quality of images on smartphones, computer displays, TVs and inkjet printers.
Advancing graphene for post-silicon computer logic: Researchers pioneer new approach for graphene logic circuits
A team of researchers from the University of California, Riverside's Bourns College of Engineering have solved a problem that previously presented a serious hurdle for the use of graphene in electronic devices.
Electrons are not enough: Cuprate superconductors defy convention
(Phys.org) —To engineers, it's a tale as old as time: Electrical current is carried through materials by flowing electrons. But physicists at the University of Illinois and the University of Pennsylvania ...
Record-setting p-type transistor demonstrated: New design boasts the highest 'carry mobility' yet measured
Almost all computer chips use two types of transistors: one called p-type, for positive, and one called n-type, for negative. Improving the performance of the chip as a whole requires parallel improvements ...
MIT physicists suggest a means for creating an electron cloaking device
Rust never sleeps—Observations of electron hopping in iron oxide hold consequences for environment and energy
(Phys.org)—Rust—iron oxide—is a poor conductor of electricity, which is why an electronic device with a rusted battery usually won't work. Despite this poor conductivity, an electron transferred to ...
LG Chem cable batteries may reshape mobile designs
Graphene battery demonstrated to power an LED
Barrier to faster graphene devices identified and suppressed
These days graphene is the rock star of materials science, but it has an Achilles heel: It is exceptionally sensitive to its electrical environment.
New path to flex and stretch electronics: Researchers develop solution-based fabrication technique
(PhysOrg.com) -- Imprinting electronic circuitry on backplanes that are both flexible and stretchable promises to revolutionize a number of industries and make "smart devices" nearly ubiquitous. Among the ...
Making a light-harvesting antenna from scratch
(PhysOrg.com) -- Sometimes when people talk about solar energy, they tacitly assume that we're stuck with some version of the silicon solar cell and its technical and cost limitations. Not so.
